にあり、その結果メンテナンスの手間も増える。For this reason, the temperature difference between the low-temperature heat of vaporization of LNG and seawater is reduced to 4u.
The method of making 48 Ichigo 1 number of Sekis and collecting them as gravity has begun to be practiced. There are many heat engines currently in use, but they are all basically Rankine cycle. Therefore, compared to the IIQ 4ITFT, which uses a simple oven rack vaporizer that does not recover electricity, As the number of equipment such as turbines, pumps, heat exchangers, and diagnostic equipment increases, and the number of equipment that controls them also increases, vaporization equipment is becoming more complex and time-consuming, resulting in less maintenance. will also increase.
